Stems
The stem is the component on a bicycle that connects the handlebars to the steerer tube of the bicycle fork. A stem's design belongs to either a quill or threadless system, and each system is compatible with respective headset and fork designs:
Quill Stems: the stem inserts into the steerer tube which is threaded and which does not extend above the headset.
Threadless Stems: the stem clamps around the steerer tube which is not threaded and which extends above the headset.
